Changes in ocular surface after withdrawal of anti-glaucoma medications following non-penetrating deep sclerectomy.

Purpose: : To analyze the ocular surface changes in eyes after the withdrawal of anti-glaucomatous drugs when non-penetrating deep sclerectomy (NPDS) is performed.

Methods: Thirty-one patients (33 eyes) diagnosed with glaucoma that underwent NPDS were included in this prospective study. The control group included 33 eyes.

Prospective evaluation of the effectiveness of combined treatment of macular edema secondary to retinal vein occlusion with intravitreal bevacizumab and dexamethasone implants.

Purpose: To evaluate the effectiveness of in---travitreal bevacizumab injections following a single dexamethasone implant in the treatment of macular edema secondary to branch and central retinal vein occlusion.

Methods: This was a prospective interventional non-comparative study, 44 eyes of patients with naïve macular edema related to branch and central retinal vein occlusion were treated with a dexamethasone implant. Patients were followed-up at four-week intervals from the second to the sixth month.

Vittaforma Corneae keratoconjunctivitis: An emerging pathology among travelers returning from Southeast Asia.

Microsporidium keratoconjunctivitis is an very rare disease. It is related to outbreaks in Asia due to exposure to contaminated water or soil. Microsporidium keratoconjunctivitis is a a self-limited disease, but it could have long term courses.

Post-herpes neurotrophic keratopathy: Aetiopathogenesis, clinical signs and current therapies.

Neurotrophic keratopathy (NK) is a degenerative corneal disease caused by damage of trigeminal innervation. This leads to epithelial defects, ulceration and, eventually, perforation. Both herpes simplex and varicella zoster keratitis are reported to be the main causes of NK.

Ganglion cell analysis at acute episode of nonarteritic anterior ischemic optic neuropathy to predict irreversible damage. A prospective study.

Purpose: To assess the capability of ganglion cell-inner plexiform layer (GCIPL) thickness analysis by optical coherence tomography (OCT) to detect early neuronal loss in nonarteritic anterior ischemic optic neuropathy (NAION).

Methods: Sixteen patients with unilateral NAION participated in this prospective study. Complete ophthalmologic evaluation including visual acuity, visual field (VF) test, and spectral domain optical coherence tomography (SD-OCT) of peripapillary retinal nerve fiber layer (pRNFL) and GCIPL thickness were performed in the acute phase (within 1 week: 2.

Bruch's membrane opening changes and lamina cribrosa displacement in non-arteritic anterior ischaemic optic neuropathy.

Purpose: To describe the morphological changes in the lamina cribrosa (LC) and prelaminar tissue (PT) from eyes with non-arteritic anterior ischaemic optic neuropathy (NAION) using enhanced depth imaging (EDI) optical coherence tomography (OCT), and to evaluate whether these changes correlate with retinal nerve fibre layer (RNFL) thickness and visual acuity (VA).

Design/methods: A prospective case-control study was performed, including 17 study eyes with NAION and 17 control, uninvolved eyes from 17 patients. Eyes underwent scanning with Spectralis-OCT at onset, 2 and 6 months after NAION.

OCT: New perspectives in neuro-ophthalmology.

Optical coherence tomography (OCT) has become essential to evaluate axonal/neuronal integrity, to assess disease progression in the afferent visual pathway and to predict visual recovery after surgery in compressive optic neuropathies. Besides that OCT testing is considered a powerful biomarker of neurodegeneration and a promising outcome measure for neuroprotective trials in multiple sclerosis (MS). Currently, spectral-domain OCT (SD-OCT) technology allows quantification of retinal individual layers.

Ganglion cell layer analysis unmasks axonal loss in anterior optic neuritis.

Optical coherence tomography is a valuable tool for evaluating patients with neuro-ophthalmic disorders. In the acute phase of anterior optic neuritis (ON), peripapillary retinal nerve fiber layer (pRNFL) measurements can underestimate the amount of damage as axonal swelling could mask the true degree of RNFL loss. Contrary to pRNFL evaluation, we hypothesize that macular ganglion cell layer analysis could detect true neuronal loss before swelling resolution in anterior ON.

[Recurrent neurosensory macular detachment in carotid-cavernous fistula].

Case Report: A 46 year-old man was seen in the emergency department complaining of vision loss and exophthalmos in his right eye. He also complained of headache, diplopia of 4 months onset, and neurosensory detachment that resolved spontaneously the month before. The study revealed tortuous conjunctival and episcleral vessels and neurosensory macular detachment in his right eye.
