Summary
Patients with myopia undergoing laser in situ keratomileusis (LASIK) surgery experienced poor vision and light sensitivity. Preoperative evaluation is crucial for those with night blindness or photophobia to detect underlying retinal conditions.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Refractive Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery for myopia.
- Suboptimal visual acuity and increased light sensitivity can occur post-LASIK.
- Preoperative screening is essential to identify potential complications.
Observation:
- Three myopic patients developed poor vision and night blindness/photophobia after LASIK.
- Comprehensive psychophysical and electrophysiological tests were performed.
- Two patients were diagnosed with progressive conerod dystrophy.
- One patient was diagnosed with retinitis pigmentosa.
Findings:
- Undiagnosed progressive conerod dystrophy in two patients.
- Undiagnosed retinitis pigmentosa in one patient.
- LASIK exacerbated symptoms in patients with pre-existing retinal dystrophies.
Implications:
- Thorough preoperative evaluation is critical for myopic patients considering LASIK.
- Patients with night blindness or photophobia require in-depth retinal assessment before LASIK.
- Early detection of retinal conditions can prevent adverse outcomes after refractive surgery.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
