Objective: To access the efficacy of selective laser trabeculoplasty (SLT) in mild, moderate and advanced stage primary open angle glaucoma (POAG) of patients undergoing surgery at Nuestra Señora de la Luz Hospital, within the Glaucoma department during 2017 to 2020 and to evaluate rate of success at 1 year of follow-up. Methods: Retrospective, observational, descriptive, cross-sectional, and comparative study. Data were collected from 33 records of patients treated with SLT between 2017-2020 with one year of follow-up. Patient response was assessed overall and by subgroups according to subsequent severity 1 year after SLT. Treatment success was defined as the reduction of intraocular pressure (IOP) ≥20% and/or reduction of eye hypotension ≥1. Results: The rate of success per year was 51%. Reduction in IOP was observed during follow-up with a median of 14 mmHg. The reduction in IOP from month 1 to 9 was statistically significant. The reduction in medications was not significant. The decrease in IOP was more frequent in mild and moderate stages, the decrease in drug consumption was greater in moderate and advanced stages. Conclusion: In patients with mild-moderate glaucoma, SLT is an effective alternative to lower IOP, while in the subgroup of moderate-advanced glaucoma it is effective in decreasing the use of hypotensive drugs.

Septic thrombosis of transverse and sigmoid cranial sinuses associated with orbito-ocular damage in pediatric patient: A case report and literature review

[Year:2023] [Month:July-August] [Volume:97] [Number:4E] [Pages:3] [Pages No:106 - 108]

Keywords: Cellulitis, Ocular trauma, Pediatric Ophthalmology, Proptosis, Venous thrombosis

A 5-year-old patient comes with proptosis of 10 days of evolution, visual acuity of no light projection and limitation to abduction of the right eye (RE). The left eye without alterations. In the ocular ultrasound of the RE, a total detachment of the retina in a closed funnel was found. Diffuse soft tissue inflammatory involvement in orbits was observed through MRI. Intravenous antibiotic treatment with vancomycin and ceftazidime was initiated, with good clinical progress. Likewise, angio-resonance showed a failure of the central filling of the right sigmoid and transverse sinus, compatible with thrombosis. The picture is interpreted as endophthalmitis and orbital cellulitis due to trauma origin with thrombosis of transverse and right sigmoid sinuses without involvement of cavernous sinus. Transverse-sigmoid sinus thrombosis is uncommon but life-threatening. Currently, MRI and angio-resonance imaging have improved the analytical capacity of the intracranial venous sinuses.

Atypical Ocular Surface Neoplasia and Fibroxanthoma in Cornea and Conjunctiva: A Case Report

[Year:2023] [Month:July-August] [Volume:97] [Number:4E] [Pages:3] [Pages No:109 - 111]

Keywords: Atypical fibroxanthoma, Conjunctival tumor, Corneal tumor, Immunohistochemistry, Ocular surface neoplasia

We report an unusual case of a 72-year-old male with a polypoid 12 x 10 x 10 mm vascularized, well circumscribed, pink mass located at the nasal bulbar conjunctiva, limbus, and proximal cornea. The patient was diagnosed with an ocular surface squamous neoplasia T2 and atypical fibroxanthoma in both cornea and conjunctiva. We analyzed the clinical presentation, histopathological examination, diagnosis and surgical strategy. Atypical fibroxanthoma in the ocular surface is a rare quite unique clinical finding. Prompt diagnosis and adequate management is important for ocular preservation. Although atypical fibroxanthoma is typically benign, recurrence and even systemic metastasis can occur.

Bee Sting Ocular Trauma: A Novel Presentation and Literature Review

[Year:2023] [Month:July-August] [Volume:97] [Number:4E] [Pages:3] [Pages No:112 - 114]

Keywords: Bee sting, Eye trauma, Endothelitis

   DOI: 10.5005/rmo-11013-0056  |  Open Access |  How to cite  | 


The objective of this study was to report on the evolution of a bee sting injury and retained stinger apparatus in the cornea that had good anatomical and functional results with appropriate management. Case report and literature review are presented. A 77-year-old patient presented after being stung by a bee in the right eye for 2 hours. His AVMC was 20/30. Slit-lamp examination showed conjunctival hyperemia, stromal infiltration of the corneal limbus into the X-meridian; + + cells (16-25 cells) were evident in the anterior chamber, also confirmed the presence of a retained corneal stinger apparatus. The OCT-AS confirmed that the stinger penetrates into the anterior chamber (AC) without contacting lens or iris. Visual acuity was 20/20. The review conducted showed that eye bee sting can cause several serious complications that were detailed in this report.

Compressive Optic Neuropathy Secondary to Locally Advanced Sinonasal Squamous Cell Carcinoma Treated with Chemotherapy and Proton Therapy: Case Report

[Year:2023] [Month:July-August] [Volume:97] [Number:4E] [Pages:5] [Pages No:115 - 119]

Keywords: Compressive optic neuropathy, Intensity-modulated proton therapy (IMPT), Maxillary Sinus, Poorly differentiated squamous cell carcinoma, Sinonasal carcinoma

Objective: Case presentation of a 41-year-old male presented with headache and left hemifacial hypoesthesia of 3 weeks of evolution. Observations: In the ophthalmological examination, left eye proptosis and limitation were observed. Funduscopy revealed left papilla edema which was confirmed with optical coherence tomography. Computed tomography, brain magnetic resonance imaging and orbits demonstrated the presence of a mass in the left maxillary sinus with intracranial extension and in the left orbit, along with optical canal invasion. Endoscopic sinonasal biopsy was compatible with poorly differentiated squamous carcinoma of the maxillary sinus. With the diagnosis of compressive optic neuropathy secondary to locally advanced paranasal sinus malignancy, palliative treatment with neoadjuvant chemotherapy and proton therapy was decided by the Head and Neck Tumor Committee. Conclusion: In the event of any ophthalmological or intracranial symptom and/or sign as a first clinical manifestation, sinonasal neoplasia must be ruled out.
