As the disease progresses, the lesion increases in size and becomes more apparent to the naked eye and may become cosmetically unpleasant for the patient. Afr Health Sci. 2011; 118:17391746. 2011;25(3):3507. Figure 6. The AS was removed in 2 to 3 weeks. It is usually seen as a triangular fleshy fibrovascular proliferation from the bulbar conjunctiva onto the cornea, located mostly on the nasal side. Related: pterygium, red eye. Among them, 6 eyes received mitomycin C, and 2 eyes with short RC (patients 14 and 15) received AM or OMG to cover the muscle. Pterygia are fibrovascular proliferations of conjunctiva encroaching onto the cornea, causing ocular discomfort and vision impairment with a global prevalence of Figure 4. All Rights Reserved. The preoperative severity of pterygium (Tan grading system) was mild/atrophic (7%), moderate/intermediate (62%), and severe/fleshy (31%). 2013;120(1):2018. 2011;20(1):714. 2012;42(6):10069. The gap between the conjunctiva and the Tenon capsule was identified by grabbing the conjunctiva with two 0.12-mm forceps (Figure 1E). The opinions expressed represent the views of the individual participants, not the position of the Academy. Low-dose intraoperative mitomycin C as chemoadjuvant for pterygium surgery. Clinical treatment of ocular demodecosis by lid scrub with tea tree oil. Furthermore, sealing of the gap may also be applied to primary pterygium and other cicatricial diseases manifesting the same pathologic change. No results found for the search term during this time period. Views 2. Arq Bras Oftalmol. Fibrin glue versus sutures for attaching the conjunctival autograft in pterygium surgery : a prospective observer masked clinical trial. Previously, one of us reported21 that such persistent conjunctival inflammation occurred in 11 of 27 eyes (41%) with primary pterygia and significantly more often in eyes receiving sutures than FG and that 7 of these 11 eyes resulted in complete resolution after administration of subconjunctival triamcinolone.

The lesion is not confined to the palpebral fissure. American Academy of Ophthalmology: Protecting Sight. For all eyes, epinephrine (1:1000) (Hospira Inc) was instilled for hemostasis control, whereas a 7-0 Vicryl (Ethicon; Johnson & Johnson) traction suture was placed at superior and inferior limbal sclera to achieve adequate exposure, estimate motility restriction, and put the medial rectus muscle under tension so that the cicatrix was safely released from the muscle without using a muscle hook. It is understandable why bare sclera with or without mitomycin C has high recurrence rates from 19.2%31 to 82.4%.1 However, thorough removal of the fibrovascular tissue5,6 together with CA1,4,5,9-11 or AM6,11 to cover bare sclera still results in variable recurrence rates (ie, 0%5 to 33.3%10 for CA and 9.5%6 to 52.6%11 for AM transplantation) (Table 3). KheirkhahA, CasasV, ShehaH, RajuVK, TsengSCG. Patients One hundred and forty one patients (258 eyes) were surveyed in this retrospective, Int Ophthalmol Clin. The glue is a blood-derived product and carries the risk (however minimal) of viral and prion disease. After that, several strategies have been advocated to curtail recurrence. 2. ( 2015 American Academy of Ophthalmology, www.aao.org.). There is a lack of consensus in the ophthalmological community about the optimal medical and surgical management of pterygia. MiyaiT, HaraR, NejimaR, MiyataK, YonemuraT, AmanoS.Limbal allograft, amniotic membrane transplantation, and intraoperative mitomycin C for recurrent pterygium. Surgical removal is considered for the following conditions: Surgical techniques include the following: A 45-year-old patient presented with hyperemia, foreign body sensation, and itchiness in her right eye without improvement after artificial tears. From 2005 to 2008 when FG was available, the FG/AS group (13 eyes) received sealing of the gap by FG and AS without thorough removal of fibrovascular tissue. WebThis article will discuss the three most common types of cataracts (nuclear, cortical, and posterior subcapsular) as well as other less common types including anterior subcapsular, posterior polar, traumatic, congenital and polychromatic. The cap or leading edge is a flat zone on the cornea that consists mainly of fibroblasts that invade and destroy Bowmans membrane. Br J Ophthalmol. From 2002 to 2004, the AS group (10 eyes) received thorough removal of fibrovascular tissue and AS to seal the gap. Ajayi Iyiade A, Omotoye Olusola J. Small pterygia without visual impairment can be treated symptomatically with artificial tears and ocular lubricants. Randomised controlled study of conjunctival autograft versus amniotic membrane graft in pterygium excision. Persistent conjunctival inflammation at the 1-month visit was graded as 0 (none), I (mild), II (moderate), or III (severe) as reported.21 The RC was measured in millimeters from the recurrent pterygial head to the clinically evident caruncle (Figure 4D and E) by displaying the external photograph of the extreme gaze in Microsoft Office Powerpoint 2003 (Microsoft Corp) (height, 3.75 in; width, 5 in; and magnification, 67%) and using E-ruler 1.1 (http://www.mycnknow.com).

A prospective, randomized, controlled, clinical trial in primary pterygia using RS to seal the gap is under way to test this hypothesis. Amniotic membrane transplantation alone was successful in 23 eyes with residual conjunctiva of 27.8(10.1) mm, which was significantly longer than those in 6 cases in which amniotic membrane transplantation failed (13.1[11.4] mm, P=.007) and those in 8 cases in which amniotic membrane transplantation was successful but that required an additional conjunctival autograft or oral mucosal graft (10.9[10.4] mm, P=.001). 2009;49(1):2130. Key surgical steps. Medical treatment for symptomatic children with small pterygia includes use of artificial tears and weak topical steroids to reduce inflammation and improve comfort. San Francisco: American Academy of Ophthalmology; 2015. Indications for surgery include the following: Primary pterygium. External photographs were taken at primary and extreme right and left gazes at 10 magnification under slitlamp examination using a Coolpix 5000 camera (Nikon Corp). DEPARTEMEN ILMU KESEHATAN MATA FAKULTAS Pattern of eye diseases among welders in a Nigeria community. In contrast, for eyes without sufficient RC, conjunctival autograft (CA) (C and D) or oral mucosal graft (OMG) (E and F) is used. Correspondence: Scheffer C. G.

WebPterygium/surgery; Autografts; Transplantation, autologous; Mitomycin/therapeutic use; Fibrin tissue adhesive; Recurrence New grading system to improve the surgical outcome of multirecurrent pterygia. Terms of Use| Recurrence was graded as G1 (normal), G2 (fine episcleral vessels), G3 (conjunctival recurrence), or G4 (corneal recurrence) as described.4 Diplopia was graded as 0 (none), D1 (diplopia 20 to 40 from the primary gaze), D2 (diplopia <20 from but not at the primary gaze), or D3 (diplopia at the primary gaze) as described.13 The caruncle morphological characteristics were graded as C1 (normal elevated dome shape, Figure 4A), C2 (normal elevated dome shape), but the semilunar fold was displaced toward the limbus, Figure 4B), or C3 (flattened, Figure 4C). Pterygium & Pinguecula Surgery Recovery Timeline EyeRounds Online Atlas of Ophthalmology. A C1 caruncle was achieved in 17 of 21 eyes (81%) that had flattened caruncles before surgery. As an important point of distinction, a probe can be passed beneath a pseudopterygium near the limbus, while this is impossible in true pterygium. Published July 19, 2021 New Multi-Step Pterygium Grading System Could Dictate Treatment Based on slit-lamp imaging, the approach relied on several markers to determine disease severity. Malays J Med Sci. YamadaM, ShinodaK, HatakeyamaA, NishinaS, MashimaY. ( 2015 American Academy of Ophthalmology, www.aao.org. Prevalence of and factors associated with pterygium in adult Chinese: the Beijing Eye Study. B. Gelatinous. MMP-9 expression did not differ between T grades or V grades. During mean (SD) follow-up of 27.5(20.5) months, 30 of 32 eyes (94%) achieved total success without recurrence and diplopia and normal caruncle in 17 of 21 eyes (81%) with abnormal caruncle before surgery. 90 Based on the external Healing time after pterygium surgery depends somewhat on how much tissue was removed, your personal health and healing ability, and A small pterygium has few symptoms and no harmful effects. Correlation among the variables was analyzed by the Pearson or Kendall tau correlation procedure when appropriate. Image License and Citation Guidelines. Arq Bras Oftalmol. For pain, oral nonsteroidal anti-inflammatory drugs are given in pediatric doses according to body weight. KheirkhahA, BlancoG, CasasV, TsengSC. But it can also appear on the other side of your eye too. A resident article published in the Ophthalmic Pearls section will satisfy the RRC requirements for resident scholarly activity. The patient treated with pterygial excision with conjungtival autograft + 5FU + symblepharectomy + amniotic membrane graft + Subconjunctival injections of triamcinolone acetonide (Bristol-Myers Squibb) in a total amount between 8 and 12 mg, subdivided into 3 depots in superior and inferior fornices and nasal caruncle, were performed, as reported,21 in the office if the surrounding conjunctiva exhibited persistent inflammation at 1-month postoperative or subsequent visits. The caruncle (head) is intentionally dragged to the limbus by a forceps to enact the recurrence (C). Our findings highlight the importance of the fibrovascular tissue emanating from the caruncle in contributing to pterygium growth and demonstrate the effectiveness of sealing the gap in combating pterygial recurrences. Representative surgical outcome in the running suture group. Customize your JAMA Network experience by selecting one or more topics from the list below. Previous studies have indicated that numerous risk factors are associated with pterygium, including UV radiation, 30, 31 environmental irritants such as dust and wind, 13 viral agents, 32, 33 familial and hereditary factors, 34 and immunological and inflammatory factors. 35, 36 GaoY-Y, Di PascualeMA, LiW, The grading proposed by Tan et al1 is clinically useful for primary pterygia but was not suitable for recurrent pterygia because episcleral vessels were not visible in most of the 32 eyes (Figure 4).

Pterygium Surgical management of pterygium. 2015;2015:891582. Am J Ophthalmol. This video illustrates the PERFECT for pterygium technique. A pterygium (from the Greek, pterygos, little wing) is a wing-shaped, vascular, fleshy growth that originates on the conjunctiva and that can spread to the corneal limbus and beyond. However, it is unclear from the scientific literature how effective surgical intervention is in correcting astigmatism. WebWe would like to show you a description here but the site wont allow us. Pterygium: epidemiology prevention and treatment - PMC Materials and Methods 2.1. Br J Ophthalmol. No difference was found in RC between the last 2 groups (P=.50). Surgical strategies for fornix reconstruction based on symblepharon severity. The prevalence of pterygium was found to be 10.2% in the world, with highest prevalence in low altitude regions (Liu et al, 2013). Without sufficient RC, epithelial healing came only from superior and inferior fornices, and delayed epithelization might lead to persistent inflammation and scarring, triggering recurrence when the gap is not sealed. Shiratori CA, Barros JC, Loureno Rde M, Padovani CR, Cordeiro R, Schellini SA. Conjunctival and corneal intraepithelial neoplasm (CIN) (. Compared with adults, children have an increased number of mast cells. Tobramycin and dexamethasone ointment (Alcon Laboratories Inc) was applied in the eye. American Academy of Ophthalmology, 20102011). Multi-Step Pterygium Grading System Could Dictate Treatment Cornea. In our clinic, we advise the following postsurgical regimen: tobramycin sulfate 0.3% drops 6 times per day for 15 days; 1% prednisolone acetate drops 4 times per day for a week, then tapered over 3 weeks; and 0.5% carboxymethylcellulose sodium drops 6 times a day for a month. 2002;34(1):436. Eye (Lond). That was why RS was used to seal the gap and found to be effective in restoring a normal caruncle because of the natural tendency of the Tenon capsule to retract posteriorly (Figure 1C and F). This finding explained why additional CA or OMG was necessary and achieved 100% success in 8 eyes with a short RC of 10.9(10.4) mm, which was also significantly less than those eyes successfully treated by AM transplantation alone (P=.001). Early in the disease process, pterygia are usually asymptomatic; however, there can be signs of dry eye (such as burning, itching or tearing) as the lesion causes irregular wetting of the ocular surface. Correlation of Caruncle Morphological Findings With RC, RH Ratio, Diplopia, and Surgical Outcome, Table 3. Pterygium comes from the Greek word meaning wing, pterygos. WebPterygium is an abnormal growth of tissue on the conjunctiva (the clear membrane that covers the white of the eye) and the adjacent cornea (the clear front surface of the eye). Besides patient demographics,16,17 ethnic and environmental factors,18 pterygium morphological characteristics,1 different surgeons,19 and postoperative regimen,20-22 we wonder whether there might be as-yet-unknown surgical variables that contribute to such variable outcomes. American Academy of Ophthalmology Future studies are needed to determine whether the caruncle grading can also refine the grading of primary pterygia. et al. In a linear regression, the extent of LPS was positively correlated with MMP-9 grades (r = 0.315, P = 0.026). A meta-analysis of pooled data from 20 studies, encompassing more than 900,000 cases in 12 countries, found an overall prevalence of 10.2%, with a slightly higher rate among men than women.2.

Another theory suggests that increased P53 expression, along with a paucity of tumor suppressor gene, facilitates the abnormal proliferation of limbal epithelium. 5 Yadav AR et al. ( 2015 American Academy of Ophthalmology, www.aao.org. Mitomycin C was used in 7 eyes in the AS group, 6 eyes in the AS/FG group, and 1 eye in the RS group (ie, relatively more in the AS/FG group). The peak incidence of primary pterygium lies between the ages of 20 and 40 years; outside of that range, the condition is rarely seen in children and more commonly in persons over the age of 40 years.3 However, the risk factors noted above can particularly affect children who play outdoors. The condition is often asymptomatic, especially early in its development. Tsai YY, Lin JM, Shy JD.

Scleral graft patch is placed in severe cases of scleral thinning. As an alternative, we have had good results with the older technique of conventional bare sclera pterygium excision. In an eye with severe symblepharon, conjunctival scar, RCof 0, and D3 diplopia before surgery (E, patient 5), the same surgery results in no recurrence but a depressed hollow space in the caruncle area (F), as evidenced by the pooling of fluorescein solution (G) and incomplete eyelid closure (H, marked by bracket). Compared with all reported studies, our surgical technique had the following 2 major differences. 2023 American Medical Association.

Geographical prevalence and risk factors for pterygium: a systematic review and meta-analysis. Analysis of variation in success rates in conjunctival autografting for primary and recurrent pterygium. Adjuvant therapies including mitomycin C (MMC), 5-fluorouracil (5-FU), ethanol, irradiation, and anti-angiogenic agents, among others, are used to reduce recurrence rate, but there is insufficient evidence that one is superior (Kaufman et al, 2013). Compared with the AS group, the FG/AS group had significantly more recurrence (P<.001), diplopia (P=.01), and persistent inflammation (P=.04). GaoY-Y, Di PascualeMA, LiW, The procedure is done in 3 logical segments: pterygium and extensive Tenon removal, retrieval of a very large and very thin graft, and finally the reconstruction of the pterygium site, including a new semilunar fold to obtain the optimal cosmetic result.
