Presentation
Inheritance - congenital achromatopsia is transmitted in an autosomal-recessive trait Presentation - patients present in early childhood with nystagmus, abnormal visual behaviour or photophobia. Acuity is less than 20/200. [patient.info]
Abnormal electrooculographic (EOG) findings are universally present in patients with Best's disease regardless of the clinical presentation, and are thus decisive in the differential diagnosis. [reviewofophthalmology.com]
Patients with any pattern dystrophy of the RPE may present with drusen-like deposits and pigmentary changes. [optometricmanagement.com]
While Stargardt’s disease typically presents in the first or second decades, multifocal pattern dystrophy presents in the fourth to sixth decades. Effect on vision. [reviewofoptometry.com]

Treament with anti-vegf therapy has shown to decrease macular swelling and improve visual acuity. [38] Treatment of CNV with PDT should be considered with caution as vitilleform lesions treated with PDT without any components of CNV may have a negative [eyewiki.aao.org]
Eyes
- Peripheral Vision Loss
The extent and rate of vision loss vary greatly among individuals with juvenile retinoschisis. Central vision is almost always affected. Peripheral vision loss occurs in about half of all cases. [retinaaustraliansw.com.au]
Skin
- Blister
The spaces created by the separated layers are often filled with blisters and ruptured blood vessels that can leak blood into the vitreous body (the transparent, colourless mass of jelly-like material filling the centre of the eye). [retinaaustraliansw.com.au]

Treatment
Treatment Treatment Options: No treatment is available for the macular disease but low vision aids should be considered for appropriate individuals. [disorders.eyes.arizona.edu]

Because of the bilateral subfoveal localization no laser treatment was advised. Usually, good visual acuity is maintained in this uncommon inherited macular disease. However, acute visual loss can be caused by the ingrowth of subretinal new vessels. [ncbi.nlm.nih.gov]
(click here for Inheritance Pattern) TREATMENT At this time, there is no treatment for juvenile retinoschisis. However, in some cases, surgery can repair retinal detachments. [retinaaustraliansw.com.au]

These entities typically occur in midlife and carry a good visual prognosis in at least one eye. [reviewofophthalmology.com]
This delineation is key because of the better visual prognosis associated with multifocal pattern dystrophy. A better prognosis is also found with multifocal pattern dystrophy when compared with basal laminar drusen. [reviewofoptometry.com]
The prognosis for pattern dystrophies is good, with patients maintaining reading-level vision in at least one eye throughout the remainder of their life. 3 This patient has not yet returned to the clinic. OM References available upon request. [optometricmanagement.com]

They are characterized predominantly by changes in the posterior pole of genetic etiology, and are often bilateral and symmetrical. [atlasrleye.com]
Both are characterized by irregular-shaped, triradiate, yellow, fleck-like lesions of variable size and shape within the posterior pole and concentrate around the retinal vascular arcades. 3,18 While the two conditions are quite similar in terms of etiology [reviewofoptometry.com]
Etiology The PRPH2 gene (also known as RDS) provides instructions for making a protein called peripherin 2. This encoded protein is a cell surface glycoprotein found in the outer segment of both rod and cone photoreceptor cells. [eyewiki.aao.org]

Next, this gene will be identified and its function in the retina determined as the first step in developing means of treatment and prevention. [retinaaustraliansw.com.au]
It also holds the promise of enabling clinicians to provide better risk assessments and develop and selectively deploy new therapeutics to either prevent or slow the disease and reduce the threat of vision loss. [healio.com]
