AF imaging in CSC demonstrates different patterns according to the course of the disease, reflecting RPE and outer retinal changes. Combining two different methods of AF imaging could predict recent or former CSC episodes and may be a non-invasive technique for monitoring CSC and performing differential diagnosis.

The marked increase in the intensity of fibrosis observed in the secondary biopsy specimens of all cases was the result of the tissue repair reaction against surgical manipulation rather than the effect of the silicone tube.

Objective: We present a patient who developed visual loss after carbon monoxide (CO) poisoning and was treated with hyperbaric oxygen. Clinical Presentation and Intervention: A 21-year-old woman poisoned with CO (with coma lasting 4 h and carboxyhemoglobin level 46%) developed seizures and cortical blindness 3 days after poisoning. Four years later, her visual acuity was 0.2 in both eyes. An ¹⁸F-fluorodeoxyglucose positron emission tomography (PET) scan showed reduced metabolism in the bilateral posterior temporal and occipital lobes. The patient received a total of 50 hyperbaric oxygen sessions over 3 months for visual loss and the visual acuity improved to 0.5 in both eyes. In addition, increased metabolism was detected in the brain in post-treatment PET scans. Conclusion: PET documented brain hypoperfusion 4 years after CO poisoning and hyperbaric oxygen therapy improved visual acuity. However, we cannot endorse routine use of hyperbaric oxygen for such patients, until results of further clinical trials demonstrate efficacy of hyperbaric oxygen in CO-induced chronic brain injury.

The OTS, which was designed to predict visual outcomes of general ocular trauma, may also provide reliable information about the prognosis of deadly weapon-related open-globe injuries with intraocular foreign bodies.
