Effects of Upper Eyelid Blepharoplasty on Contrast Sensitivity in Dermatochalasis Patients.

Objectives: To evaluate the impact of upper eyelid blepharoplasty on contrast sensitivity in dermatochalasis patients.

Materials And Methods: Best corrected visual acuity, ophthalmologic examination, eyelid examination, lash ptosis, contrast sensitivity using sine-wave contrast sensitivity chart, keratometric parameters, and corneal aberrations of 34 eyes of 34 patients who underwent upper eyelid blepharoplasty due to dermatochalasis in our clinic between the years 2014 and 2018 were evaluated preoperatively and at postoperative 3 months.

Results: Twenty-three (68%) of the patients were females and 11 (32%) were males.

Viral nucleic acid analysis with PCR in lacrimal tissue and nasal swab samples of primary acquired nasolacrimal duct obstruction cases.

Purpose: To evaluate the role of viral infections in the pathogenesis of primary acquired nasolacrimal duct obstruction.

Methods: The study included 48 patients diagnosed with primary acquired nasolacrimal duct obstruction undergoing dacryocystorhinostomy surgery. Prior to dacryocystorhinostomy surgery, nasal swab sample was taken from the inferior meatus at the same side.

SPONTANEOUS CLOSURE OF MACULAR HOLE IN A PATIENT WITH MACULAR TELANGIECTASIA TYPE 2.

Purpose: To present a case of macular hole associated with macular telangiectasia Type 2 (Mac-Tel 2) which underwent spontaneous closure.

Methods: A 58-year-old woman is admitted with complaints of blurred and distorted vision. Optical coherence tomography, fundus autofluorescence, and optical coherence tomography angiography were performed for diagnosis and follow-up.

Optical Coherence Tomography Angiography Findings in Type-2 Macular Telangiectasia.

Objectives: To evaluate the vascular changes of idiopathic macular telangiectasia type 2 (MacTel 2) patients with optical coherence tomography angiography (OCTA) and correlate these changes with the findings of spectral domain optical coherence tomography (SD-OCT).

Materials And Methods: Simultaneous SD-OCT and OCTA images of 10 eyes of 6 patients who were diagnosed as MacTel 2 in Ankara University Faculty of Medicine, Department of Ophthalmology were obtained and graded according to the OCTA grading system for MacTel 2.

Results: Ten eyes of 6 patients were included.

The use of optical coherence tomography angiography in pachychoroid spectrum diseases: a concurrent comparison with dye angiography.

Purpose: The study objective was to compare dye angiography and optical coherence tomography angiography (OCTA) in detecting choroidal neovascuarization (CNV) in patients presenting with pachychoroid features and flat irregular pigment epithelial detachment (PED).

Methods: Nineteen eyes of 17 patients, presenting with flat PED and pachychoroid features, and without age-related macular degeneration or any other degenerative change, were analyzed. Fuorescein angiography (FA)/Indocyanine green angiography (ICGA) and OCTA were performed during the same visit.

Exudative retinal detachment.

Exudative retinal detachment develops when fluid collects in the subretinal space. The subretinal space between the photoreceptors and the retinal pigment epithelium is the remnant of the embryonic optic vesicle. In the developed eye the subretinal space is of minimal size, but it can reopen under pathological conditions that disrupt the integrity of blood-retinal barrier.

Necrotic intraocular retinoblastoma associated with orbital cellulitis.

Orbital cellulitis associated with retinoblastoma is uncommon and is characterized by noninfectious inflammation of the periorbital structures. The underlying mechanism is thought to be necrosis of the intraocular tumor, leading to intraocular and periorbital inflammation. We report 2 retinoblastoma patients who presented with an orbital cellulitis-like picture and discuss clinical characteristics, histopathologic features, and treatment.
