Diagnosis of intraocular metastases does not cause difficulties in cases of oncological anamnesis in patient withs visual complaints and a characteristic ophthalmoscopic picture. In 10-20% of cases, eccentrically located metastases, are an accidental finding, which can cause difficulties in correct diagnosis establishing. A clinical case of asymptomatic bilateral multifocal choroidal metastases of small sizes is presented. Their OCT findings and the dynamics of follow-up during polychemotherapy are described. Key words: choroidal metastasis, optical coherence tomography, polychemotherapy.

Aims: To describe the importance of optical coherence tomography and autofluorescence in the documentation of papillary colobomatous fossette. Presentation of Case: F.D.O. A 14-year-old male student is referred for evaluation of the fundus of the eye due to an alteration in the optic disc noticed by another professional who did not feel safe in the follow-up. The patient was completely asymptomatic at the time of the consultation and did not claim previous visual complaints. She denied systemic and ocular comorbidities and did not use any systemic and topical medication. Discussion: The congenital optic disc pit is a rare and typically unilateral congenital anomaly, consisting of a retinal herniation that extends into the subarachnoid space through a lamina cribrosa defect. 8,13,15,16 Although this condition, in most cases, does not present complications and remains asymptomatic, it can sometimes worsen with a significant decrease in visual acuity. This more serious condition can be characterized by important macular alterations, such as serous retinal detachment, cystic degenerations and degenerative pigmentary alterations. 14,16,17,18 The patient in the present report did not have any visual complaints and did not present severe structural and functional retinal damage, which highlights the importance of early diagnosis. Conclusions: The colobomatous papilla pit is characterized by the presence of isolated cavities in the optic disc head secondary to a developmental disorder of the primitive epithelial papilla. Its incidence is 1:10,000 people without sexual or racial predilection. It presents, in most cases, asymptomatic, unilateral in 85-95% of cases and rarely with more than one pit per disc.

Retinal Pathology

Purpose: Epiretinal membrane (ERM) is a common retinal finding for patients older than 50 years. Disorganization of the retinal inner layers (DRIL) has emerged as a novel predictor of poor visual acuity (VA) in eyes with inner retinal pathology. The aim of our study is to correlate preoperative DRIL with visual outcomes after ERM surgery. Methods: Medical records and optical coherence tomography (OCT) images of 81 pseudophakic patients who underwent treatment of idiopathic ERM were reviewed. Preoperative DRIL on OCT was correlated with VA at baseline and at 3 and 6 months after ERM surgery. DRIL was defined as the loss of distinction between the ganglion cell–inner plexiform layer complex, inner nuclear layer, and outer plexiform layer. DRIL severity was based on its extent within the central 2-mm region of a transfoveal B-scan (absent/mild: <one-third, severe: >one-third horizontal width). Results: Review of preoperative OCT showed severe DRIL in 41% and absent/mild DRIL in 59%. Severe DRIL was associated with worse baseline VA ( P < .001). Preoperative VA and DRIL status at baseline were both predictors of postoperative VA at follow-up time points ( P < .001). Severe DRIL was associated with significantly less improvement in VA at 6 months (–0.23 logMAR for absent/mild vs –0.14 for severe DRIL). Conclusions: Presence of severe preoperative DRIL correlates with worse baseline VA in patients with ERM and reduced VA improvement at 6 months. DRIL can be a strong predictor of long-term poor visual outcomes in ERM surgery.

The introduction of anterior-segment optical-coherence tomography (AS-OCT) has led to improved assessments of the anatomy of the iridocorneal-angle and diagnoses of several mechanisms of angle closure which often result in raised intraocular pressure (IOP). Continuous advancements in AS-OCT technology and software, along with an extensive research in the field, have resulted in a wide range of possible parameters that may be used to diagnose and follow up on patients with this spectrum of diseases. However, the clinical relevance of such variables needs to be explored thoroughly. The aim of the present review is to summarize the current evidence supporting the use of AS-OCT for the diagnosis and follow-up of several iridocorneal-angle and anterior-chamber alterations, focusing on the advantages and downsides of this technology.

First Time

We describe a case with complex Descemet membrane detachment (DMD) which persisted despite initial two failed surgical attempts to appose the ocular tissues. However, over time, tissue alignment was obtained spontaneously. A 60-year-old woman, operated trabeculectomy, had a total DMD intraoperatively during a complicated cataract surgery. Initial attempt to DM repositioning with intracameral air injection failed. Anterior Segment Optical Coherence Tomography (ASOCT) showed detachment of both DM and pre-Descemet’s layer (PDL). After consultation with a corneal surgeon, patient was again attempted for Intra-operative Optical Coherence Tomography (iOCT)-guided settlement of DMD with intracameral air which again failed. So, the patient was registered for lamellar corneal transplant, but at 3 months follow-up, DM had spontaneously attached, confirmed on ASOCT. This case shows for the first time that even complex DMDs involving PDL, can spontaneously appose despite failed surgical interventions.
