Digital analysis of unilateral ptosis repair: external levator advancement vs. Müller's muscle conjunctival resection.

PURPOSE: Evaluation of lid contour and marginal peak point changes to compare outcomes of external levator advancement and Miiller's muscle conjunctival resection surgery in unilateral ptosis. METHODS: We reviewed the charts of unilateral ptosis patients who underwent external levator advancement or Miiller's muscle conjunctival resection. Eyelid contour analysis was conducted on preoperative and 6-month postoperative digital images. This was performed with the multiple margin reflex distances technique, measuring the vertical distance from a line intersecting the center of the pupil to the eyelid margin at 10 positions at 2 mm intervals. The marginal peak point changes were analyzed digitally using the coordinates of the peak point according to the pupil center. Each position's mean distance was compared preoperatively, postoperatively, and with the fellow eyelid. RESULTS: Sixteen patients underwent external levator advancement and 16 patients had Miiller's muscle conjunctival resection. The mean margin reflex distance was improved by both techniques (1.46 vs. 2.43 mm and 1.12 vs. 2.25 mm, p=0.008 and p=0.0001 respectively) and approached that of the fellow eyelid (2.43 vs. 2.88 and 2.25 vs. 2.58 mm, p=0.23 and p=0.19, respectively). However, statistically significant lid margin elevation was limited to between the N6 and T6 points in the external levator advancement group. Whereas, significant elevation was achieved along the whole lid margin in the Miiller's muscle conjunctival resection group. The marginal peak point was shifted slightly laterally in the external levator advancement group (p=0.11). CONCLUSIONS: Both techniques provide effective lid elevation, however, the external levator advancement's effect lessens toward the canthi while Müller's muscle conjunctival resection provides more uniform elevation across the lid margin. The margin reflex distance alone is not sufficient to reflect contour changes.

Complicated trabeculectomy converted into ab externo cyclodialysis.

The creation of a scleral flap during trabeculectomy can be complicated by a buttonhole, partial amputation at the limbus, and extensive thinning. In some cases, the procedure must be aborted to prevent more serious postoperative complications. This report describes a technique of converting complicated trabeculectomy into ab externo cyclodialysis. A 41-year-old patient with congenital glaucoma presented with a perforated scleral wall with the choroidal tissue exposed during the dissection of the partial-thickness scleral flap. By using a Barraquer cyclodialysis spatula through the scleral perforation, the choroid was separated from the sclera up to the scleral spur over 30° into the anterior chamber. The sclera and conjunctiva/Tenon were sutured with 10-0 nylon single sutures. Two months later, the intraocular pressure was reduced to 16 mmHg with no hypotensive topical medications. This case illustrates an alternative approach to managing a flap-related perioperative complication in trabeculectomy, which yielded good early results.

Primary basal cell carcinoma of the caruncle: case report and review of the literature.

We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered.

Two-Year Progression of Dry Eye Disease in Dry Eye Assessment and Management Study.

PURPOSE: The purpose of this study was to evaluate the progression of dry eye disease (DED) symptoms and signs over 2 years through a secondary analysis of data collected from the Dry Eye Assessment and Management study. METHODS: Participants who were assigned to omega-3 fatty acid in the first year were rerandomized in the second year to either continue with omega-3 fatty acid or switch to placebo. At baseline, 3, 6, 12, 18, and 24 months, DED symptoms were evaluated by using the Ocular Surface Disease Index and the Brief Ocular Discomfort Index (BODI). DED signs were assessed using conjunctival staining, corneal staining, tear break-up time, Schirmer testing, and keratography measures. Medication usage was documented at each visit. Because the treatment and placebo groups displayed no statistical differences in both signs and symptoms, data from the 43 participants were combined to assess longitudinal changes in symptoms and signs. RESULTS: At 3 months after omega-3 fatty acid treatment, there were significant improvements from baseline in Ocular Surface Disease Index and Brief Ocular Discomfort Index scores (all P ≤ 0.002) and less use of artificial tears or gel ( P = 0.02), but between 3 and 24 months, no significant changes in symptoms and treatments were observed ( P ≥ 0.06). Except for a significant improvement in conjunctival staining score over 2 years ( P = 0.001), there were no significant sign changes in corneal staining ( P = 0.32), tear break-up time ( P = 0.43), Schirmer test ( P = 0.09), and additional measures (all P ≥ 0.07). CONCLUSIONS: We did not observe a progression of DED signs or symptoms over a 2-year period, except for a probable placebo response in symptoms in the first 3 months and an improvement in conjunctival staining score.

Conjunctival ultraviolet autofluorescence as a biomarker of outdoor exposure in myopia: a systematic review and meta-analysis.

Outdoor exposure is considered the primary modifiable risk factor in preventing the development of myopia. This effect is thought to be attributed to the light-induced synthesis and release of dopamine in the retina. However, until recent years, there was no objective quantifiable method available to measure the association between time spent outdoors and myopia. It is only recently that the conjunctival ultraviolet autofluorescence (CUVAF) area, serving as a biomarker for sun exposure, has begun to be utilized in numerous studies. To provide a comprehensive summary of the relevant evidence pertaining to the association between the CUVAF area and myopia across different geographic regions and age groups, a systematic review and meta-analysis were conducted. The search encompassed multiple databases, including MEDLINE, SCIENCE DIRECT, GOOGLE SCHOLAR, WEB OF SCIENCE, and SCOPUS, and utilized specific search terms such as "conjunctival ultraviolet autofluorescence", "CUVAF", "UVAF", "objective marker of ocular sun exposure", "myopia", "degenerative myopia", and "high myopia". The bibliographic research included papers published between the years 2006 and 2022. A total of 4051 records were initially identified, and after duplicates were removed, 49 articles underwent full-text review. Nine articles were included in the systematic review. These studies covered myopia and outdoor exposure across different regions (Australia, Europe and India) with a total population of 3615 individuals. They found that myopes generally had smaller CUVAF areas compared to non-myopes. The meta-analysis confirmed this, revealing statistically smaller CUVAF areas in myopic patients, with a mean difference of - 3.30 mm2 (95% CI - 5.53; - 1.06). Additionally, some studies showed a positive correlation between more outdoor exposure and larger CUVAF areas. In terms of outdoor exposure time, myopic patients reported less time outdoors than non-myopic individuals, with a mean difference of - 3.38 h/week (95% CI - 4.66; - 2.09). Overall, these findings highlight the connection between outdoor exposure, CUVAF area and myopia, with regional variations playing a significant role. The results of this meta-analysis validate CUVAF as a quantitative method to objectively measure outdoor exposure in relation with myopia development.

Ophthalmic Manifestations of Monkeypox Virus Infection: A Cases Series.

This retrospective case series aims to describe the ophthalmic manifestations of the Monkeypox virus infection in seven patients evaluated in two countries of South America (Colombia and Brazil). Two had skin lesions in the eyelid, and five had conjunctivitis. None had intraocular involvement. Three of seven patients had a history of Human Immunodeficiency Virus infection, and all patients had lesions in the genital region, suggesting sexual-contact transmission. In 6 of 7 cases, conjunctival RT-PCR was positive for the Monkeypox virus, including one case without conjunctival vesicles. In all cases, lesions resolved without complications, and just two required antiviral treatment. All patients demonstrated improvement without complications. RT-PCR positivity in conjunctiva demonstrated the presence of the Monkeypox virus, suggesting that ocular-mediated transmission could be plausible. Ophthalmologists should be aware of this ophthalmic manifestation.

Definition and Diagnostic Criteria for Pediatric Blepharokeratoconjunctivitis.

Importance: Pediatric blepharokeratoconjunctivitis (PBKC) is a chronic, sight-threatening inflammatory ocular surface disease. Due to the lack of unified terminology and diagnostic criteria, nonspecific symptoms and signs, and the challenge of differentiation from similar ocular surface disorders, PBKC may be frequently unrecognized or diagnosed late. Objective: To establish a consensus on the nomenclature, definition, and diagnostic criteria of PBKC. Design, Setting, and Participants: This quality improvement study used expert panel and agreement applying the non-RAND modified Delphi method and open discussions to identify unified nomenclature, definition, and definitive diagnostic criteria for PBKC. The study was conducted between September 1, 2021, and August 14, 2022. Consensus activities were carried out through electronic surveys via email and online virtual meetings. Results: Of 16 expert international panelists (pediatric ophthalmologists or cornea and external diseases specialists) chosen by specific inclusion criteria, including their contribution to scientific leadership and research in PBKC, 14 (87.5%) participated in the consensus. The name proposed was "pediatric blepharokeratoconjunctivitis," and the agreed-on definition was "Pediatric blepharokeratoconjunctivitis is a frequently underdiagnosed, sight-threatening, chronic, and recurrent inflammatory eyelid margin disease associated with ocular surface involvement affecting children and adolescents. Its clinical spectrum includes chronic blepharitis, meibomitis, conjunctivitis, and corneal involvement ranging from superficial punctate keratitis to corneal infiltrates with vascularization and scarring." The diagnostic criteria included 1 or more suggestive symptoms accompanied by clinical signs from 3 anatomical regions: the eyelid margin, conjunctiva, and cornea. For PBKC suspect, the same criteria were included except for corneal involvement. Conclusions and Relevance: The agreements on the name, definition, and proposed diagnostic criteria of PBKC may help ophthalmologists avoid diagnostic confusion and recognize the disease early to establish adequate therapy and avoid sight-threatening complications. The diagnostic criteria rely on published evidence, analysis of simulated clinical cases, and the expert panel's clinical experience, requiring further validation with real patient data analysis.

Effects of topical ketorolac tromethamine on tear parameters, meibography, goblet cell density, and conjunctival oxidative stress in healthy dogs.

OBJECTIVES: The objective of the study was to evaluate whether a twice-daily instillation of 0.45% preservative-free ketorolac tromethamine (FKT) or 0.4% benzalkonium chloride-preserved ketorolac tromethamine (BACKT), every 12 h for 30 days may affect tear film parameters and the meibography in healthy dogs. Additionally, we assessed whether the same treatments irritated the ocular surface, affected goblet cell density (GCD), and the levels of oxidative stress biomarkers (OSB) in the conjunctiva of the same dogs. PROCEDURES: Experimental and masked comparison study. In 11 healthy dogs baseline values of the lipid layer thickness, tear meniscus height, non-invasive tear breakup time (NI-TFBT), and the meibomian gland (MG) loss were assessed by OSAvet®. For each dog, one eye received 40 µL of BACKT, while the other received 40 µL FKT, every 12 h for 30 consecutive days. Tear parameters and meibography were repeated 15, 30, and 60 days post-treatments. Conjunctival hyperemia and blepharospasm were monitored at the same time points. At baseline and Day 30, a conjunctival biopsy was collected for GCD and OSB determination. RESULTS: Conjunctival hyperemia and blepharospasm were not observed. At Day 15, the MG loss increased only in FKT-treated eyes (p < .001). On Day 30, both treatment groups showed increased MG loss, shortened NI-TFBT, and reduced GCD and catalase (p < .05). At Day 30, BACKT-treated eyes showed lower levels of superoxide dismutase (SOD) (p = .006) and higher levels of malondialdehyde (MDA) (p = .02). Differences between treatments were not observed for any parameter at any time point (p > .05). 60 days after treatment, OSAvet® parameters tended to return to values assessed at baseline; however, significant differences remained for MG loss (p < .05). CONCLUSIONS: Twice-daily instillation of KT, containing or not BAC, for 30 consecutive days shortened NI-TFBT, decreased GCD, and increased the MG loss in healthy dogs. KT should be used with caution when prescribed for long periods, particularly in patients with tear film abnormalities. However, future controlled studies using KT, BAC, and other topical NSAIDs are indicated to further support this finding.

Comparison of mini-simple limbal epithelial transplantation and conjunctival-limbal autograft for the treatment of primary pterygium: a randomised controlled trial.

PURPOSE: The purpose of this double-masked, parallel randomised controlled trial was to compare the recurrence rate and other outcomes between conjunctival-limbal autograft (CLAu) and mini-simple limbal epithelial transplantation (mini-SLET) after excision of pterygium. METHODS: Eligibility criteria for participants was the presence of a primary nasal pterygium extending equally to or greater than two millimetres on the cornea on its horizontal axis from the nasal limbus. The participants were allocated into two groups (CLAu and mini-SLET) using simple randomisation with a table of random numbers. Participants and the outcome assessor were masked to the intervention. The study protocol is listed and available on https://clinicaltrials.gov (Identifier: NCT03363282). RESULTS: A total of 61 eyes were enrolled in the study, 33 underwent CLAu (group 1) and 28 mini-SLET (group 2), all eyes were analysed in each group. At 2, 3, 6 and 12 months the CLAu group exhibited a recurrence of 0%, 6.1%, 8.1% and 8.1%, while the mini-SLET exhibited a recurrence of 0%, 17.9%, 50% and 53.5% (p<0.05). There were no intraoperative or postoperative complications in either of the two groups. CONCLUSION: The findings of this study suggest that mini-SLET has a higher recurrence rate and provides no advantage over CLAu in the treatment of primary pterygium.

Results of Fibrin Glue Applied Over the Corneal Surface Immediately After Pterygium Surgery: A Novel Pain Relief Technique.

PURPOSE: The aim of this study was to compare the use of fibrin glue on the corneal epitheliectomy site at the end of pterygium surgery versus conventional eye patch regarding pain levels, need for oral analgesic medications, number of days feeling pain, and awakening due to pain after surgery. METHODS: Forty-eight eyes of 24 patients with bilateral primary pterygium were included in this prospective, randomized, double-masked controlled trial. Each eye of the same patient was randomized to the intervention or control group. The intervention group received 2 drops of fibrin glue in the epitheliectomy site at the end of surgery and an eye patch, whereas the control group was only received an eye patch. Patients returned on the first and seventh days after surgery. Pain intensity (measured using the visual pain analog scale), need for oral analgesics, the number of days the pain lasted, and quality of sleep were assessed during follow-up visits and compared between groups. Comparison analysis accounted for sex, age, pterygium grading, and comorbidities. RESULTS: Visual analog pain scale after surgery was significantly lower in eyes receiving fibrin glue (-1.58; 95% confidence interval: -2.84 to -0.32; P = 0.014). In addition, the intervention group presented a 73% lower chance of using oral analgesics (OR: 0.27; 95% confidence interval: 0.07-0.95; P = 0.041). No difference in the awakenings at night was noted ( P = 0.240) nor the mean days of ocular pain in the first week after surgery ( P = 0.474). CONCLUSIONS: Fibrin glue at the end of pterygium surgery effectively reduces pain and the need for oral analgesics compared with conventional eye patching. This study is the first to describe the results of this strategy.

Morphological and ultrastructural study of the palpebral conjunctiva of healthy domestic cats.

OBJECTIVE: To describe the morphology of the meibomian glands and goblet cells in the palpebral conjunctiva of healthy cats. ANIMALS STUDIED: Five healthy domestic cats without ocular changes that had died from causes unrelated to the study were evaluated. PROCEDURES: Forty samples were collected from upper and lower palpebral conjunctiva and 20 from palpebral fornix region in the nasal corner. The samples were processed for scanning electron microscopy (SEM), transmission electron microscopy (TEM), and histopathology. RESULTS: In the SEM analysis of the palpebral fornix, numerous points of mucous extrusion between the cell junctions were visualized, along with the presence of microvilli in the apical portions with small secretory vesicles. A homogeneous surface was highlighted, formed by the arrangement of cell contours in the form of hexagons. The grouping of goblet cells and their cytoplasmic vesicles filled with homogeneous content was visualized using TEM. Histopathology showed goblet cells interspersed with stratified epithelium accompanied by well-vascularized connective tissue. In the samples stained with hematoxylin and eosin, the meibomian glands, formed by acinar cells and with the presence of individual openings of the ducts in the eyelid margin, were easily visualized in the eyelid margins. CONCLUSIONS: This study describes the ultrastructural form of goblet cells and the morphology of the palpebral conjunctiva of healthy cats by the histopathology of the meibomian glands. This description can serve as a parameter of normality and aid in the detection of morphological alterations in these structures, as well as a parameter for comparison with other animal species.

Autologous fibrin glue versus sutures for conjunctival autograft in primary pterygium: a randomized clinical trial.

PURPOSE: To describe and compare the autologous fibrin glue and traditional sutures for conjunctival graft attachment in patients undergoing primary pterygium excision surgery. METHOD: A randomized clinical trial included patients who underwent pterygium surgery with conjunctival autologous graft (CAG). Using randomization, a single-trained surgeon performed graft fixation with autologous glue or sutures. The glue was prepared immediately before the surgery, using the patient's blood components. After centrifugation, the plasma was collected and enhanced with calcium gluconate. Postoperative assessments were performed on Days 1, 7, 21, 30 and 180. The study evaluated postoperative edema and pain and complications. The mean surgical time was compared. Recurrence of the pterygium was assessed 6 months postoperatively. RESULTS: The study evaluated 61 eyes. Thirty-three eyes underwent pterygium surgery using the glue technique, and 28 underwent the traditional suture technique. Fifty-one patients (83.60%) had successful graft adhered to at the end of follow-up. Ten patients (10/33) lost their graft in the glue group, and only 69.70% maintained graft presence in the fourth week versus 100% of the patients in the suture group (p = 0.001). Pain scores were lower in the glue group, and clinical edema was significantly higher. There was no significant difference in graft retraction or the presence of granuloma, necrosis or postoperative infection. CONCLUSION: Autologous fibrin glue is an affordable option for CAG fixation in particular contexts where commercial fibrin glue is unavailable, and it could offer advantages compared to sutures. A higher graft loss rate was observed and might be related to topical anesthesia, and improvements to the technique are needed.

Analysis of antibiotic resistance and genetic profile of conjunctival bacteria flora before and after cataract surgery.

PURPOSE: To analyze antibiotic resistance and genetic profile of conjunctival bacteria flora before and after cataract surgery with the focus on coagulase-negative staphylococci (CNS) during cataract surgery and discuss the implications of this colonization as a potential risk of acquiring endophthalmitis. METHODS: After approval of the institutional review board and informed consent from patients had been obtained, conjunctival swabs for culture from 59 patients undergoing cataract surgery were taken of the fellow eye at baseline (C0) and from the eye to be operated before (T0) and after (T1) irrigation with povine-iodine 5%, and at the end of surgery (T2). Genes responsible for virulence (mecA, ica and atlE) and antibiotic profile were determined; strain clonality of persistent colonizing Staphylococcus epidermidis strains was established by the Multi-locus sequence typing (MLST). RESULTS: The frequency of CNS was significantly reduced in T1 (13.6%) from 81.4% in T0 and 86.4% in C0. The frequency of mecA, ica and atlE genes was 34.4%, 37.5% and 61.4%, respectively; and methicillin phenotypic resistance was 35.4%. S. epidermidis was the most frequent species isolated in every time point. MLST revealed in 7 patients 100% coincidence of the seven alleles of the S. epidermidis isolated previous to povine-iodine 5% disinfection and at the end of the surgery. CNS isolates from T1 or T2 corresponded to the same species, antibiotic and virulence profile as those isolates from C0 or T0. CONCLUSION: Povidone-iodine 5% prophylaxis before surgery significantly reduced conjunctival contamination; in those that persisted, the source of contamination was mostly the patient's microbiota confirmed by the MLST system.

Ocular lesions in cats diagnosed with systemic sporotrichosis.

OBJECTIVES: To describe the most common ocular lesions and demonstrate the frequency of ophthalmic involvement in a group of cats with systemic sporotrichosis. ANIMALS STUDIED: Two hundred seventy-four cats diagnosed with systemic sporotrichosis. The inclusion criteria included previous positive cytopathological examination, histopathological examination, or fungal culture. PROCEDURES: In a prospective case-control study, 274 cats diagnosed with systemic sporotrichosis underwent ophthalmic evaluation and received treatment for systemic sporotrichosis. Of these animals, 63 had ocular abnormalities which were recorded, and conjunctivitis was scored from 0 to 5. Diagnostic techniques utilized included fungal culture, as well as cytopathological (10 eyes; 10 cats), and histopathological examination of the palpebral conjunctiva and eyes (2 eyes). RESULTS: Cytopathological and histopathological examination of the conjunctiva, as well as fungal culture, proved to be important tests for the detection of Sporothrix sp. Five cats without the evidence of ophthalmic abnormalities also had a positive fungal culture. The identified ocular lesions in animals with systemic sporotrichosis included increased serous discharge (79 eyes; 53 cats), blepharoconjunctivitis (33 eyes; 25 cats), conjunctivitis (39 eyes, 20 cats), blepharitis (9 eyes; 8 cats), uveitis (5 eyes; 3 cats), and Florida keratopathy-like lesions (2 eyes; 1 cat). CONCLUSION: Sporotrichosis should be considered a differential diagnosis for conjunctivitis and blepharoconjunctivitis, especially in endemic areas. Fungal culture and cytopathology of ocular discharge and histopathological examinations of the conjunctiva are important for the diagnosis of ophthalmic sporotrichosis, although not all cats underwent laboratory testing in this study. Ocular discharge could be a source of contagion transmission.

Congenital eyelid imbrication syndrome in a Hispanic newborn: case report and review of the literature.

A 6-hour newborn boy presented with bilateral overriding of the upper eyelids during sleep and spontaneous eyelid eversion. Physical examination revealed canthal tendon laxity and hyperemia of the tarsal conjunctiva of both eyes. A diagnosis of congenital eyelid imbrication syndrome (CEIS) was established. The cornea and remaining adnexal structures were healthy; therefore, conservative management with lubricant ointment was initiated. On day 4, complete resolution of upper eyelid overriding and absence of spontaneous eversion was observed. CEIS is a rare eyelid malposition disorder in which the upper eyelid overrides the lower. Most CEIS cases described in the literature present at birth, occur in Asian patients, are associated with floppy eyelid, and resolve spontaneously. The authors present the first report of CEIS in a Hispanic newborn and a literature review of previously reported cases.

Simultaneous posterior eyelid ptosis repair and strabismus surgery: a single-stage approach.

PURPOSE: Blepharoptosis with coexisting strabismus can be observed in adults, and both these conditions affect cosmetic appearance and have psychosocial effects. Both also commonly require surgery, which is typically performed using a sequential approach. This study aimed to evaluate the efficacy of simultaneous Müller's muscle-conjunctival resection with or without tarsectomy and strabismus surgery in adult patients with ptosis and coexisting strabismus. METHODS: Patients with ptosis and coexisting strabismus who underwent simultaneous Müller's muscle-conjunctival resection with or without tarsectomy and horizontal strabismus surgery were retrospectively evaluated. Analysis included measurement of the angle of deviation in prism diopters, margin reflex distance, eyelid height asymmetry, and complications following surgery. Success of Müller's muscle-conjunctival resection with or without tarsectomy was defined as a margin reflex distance of ≥3.5 and ≤5 mm with a difference between the two upper eyelids of <1 mm. Strabismus success was defined as alignment with ±10 prism diopters of orthotropia. RESULTS: The patients comprised three women and five men with a mean age of 37.12 years (range, 22-62 years). The strabismus stage of the surgery was performed first in all patients. Upper eyelid symmetry outcomes were assessed as perfect (<0.5 mm) in four patients and good (≥0.5 mm, <1 mm) in four patients. Success of Müller's muscle-conjunctival resection with or without tarsectomy was achieved in six of eight patients (75%), and strabismus success was achieved in all patients. No revision eyelid or strabismus surgery was required following simultaneous surgery in any of the patients. CONCLUSION: Müller's muscle-conjunctival resection with or without tarsectomy combined with strabismus surgery may be an alternative approach for use in patients with ptosis and coexisting strabismus.

Masquerade syndrome in ocular surface squamous neoplasia.

The aim of this study was to alert the ophthalmic community to an atypical manifestation of ocular surface squamous neoplasia, which may delay diagnosis and treatment and result in a guarded visual prognosis and significant sequelae. A 61-year-old immunocompetent man presented with an initial diagnosis of necrotizing scleritis in the right eye for 3 months. He was treated with systemic prednisone but experienced persistent pain and low visual acuity. Conjunctival biopsy of the affected region confirmed the diagnosis of invasive ocular surface squamous neoplasia, which progressed with intraocular and orbital invasion; thus, exenteration was performed. Masquerade syndrome should be suspected in patients with nodulo-ulcerative lesions of the conjunctiva and sclera. This clinical can be more aggressive, with a greater likelihood of intraocular and orbital involvement. The earlier the diagnosis and treatment, the better the patient prognosis.
