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]

History Patients with atrophic retinal holes generally present for routine ocular examinations. This type of lesion is generally an incidental finding. [eyewiki.aao.org]
Variable features of lattice lesions include abnormal pigmentation (present in 82 percent), yellow-white surface flecks (present in 80 percent) and branching white lines, which represent occluded or sheathed vessels (present in 17 percent). [reviewofophthalmology.com]

- Asymptomatic
Three of five symptomatic and all asymptomatic breaks occurred adjacent to lattice lesions. [clinicalgate.com]
Asymptomatic Retinal Breaks Asymptomatic operculated holes and atrophic round holes very rarely lead to detachment. [reviewofophthalmology.com]

Retinal detachments may be associated with congenital malformations, metabolic disorders, trauma, previous ocular surgery, vascular disease, choroidal tumors, high myopia, vitreous disease or degeneration. [institut-vision.org]
Eyes
- Scotoma
Both forms of retinoschisis cause an absolute scotoma (dense visual field defect) in the corresponding visual field to the area of retina affected, whereas, retinal detachments cause a relative scotoma “curtain effect” in the visual field. [asams.org]
This loss of our straight ahead vision is called a central scotoma - it is a gray or black spot that appears in the center of one's vision. Other vision changes involve: 1. Reading slower The speed of reading drops as GA progresses 2. [webrn-maculardegeneration.com]
CASE REPORT A 40-year-old female consulted an ophthalmologist in 2003 after realizing that she had a scotoma in the central field along with minor complaint of metamorphosis in the left eye (OS). [scielo.br]
Formal visual field testing may manifest scotomas along areas of densely involved retina. There are no specific findings on anterior and vitreous examination. [eyewiki.org]
- Photopsia
Retinal tears may occur without symptoms, but often photopsia (luminous rays or light flashes in vision) is noted. Photopsia results from mechanical stimulation of the retina by vitreoretinal traction. [aafp.org]
Some patients may present with a complaint of photopsias (flashing lights) or other visual disturbance if associated with a symptomatic posterior vitreous detachment. [eyewiki.aao.org]
This article will review how to approach the patient who has acute symptoms of vitreous floaters and photopsia. [optometricmanagement.com]
Signs & Symptoms The patient is usually over age 20 and is nearly always asymptomatic, except for possible complaints of flashing lights (photopsia). There appears to be a higher incidence of myopia in patients with lattice degeneration. [eyecaretrust.org.uk]
Photopsia, the subjective impression of flashing lights, is caused by vitreous traction on the peripheral retina. Floaters are described as "cobwebs," "spots," or "hair" in the field of vision. [reviewofophthalmology.com]

Prognosis
Prognosis - there is no progression. [patient.info]
Prognosis The ocular prognosis is poor because constriction of the visual field and visual loss are progressive and can cause blindness. Early diagnosis and successful diet treatment are important prognostic factors. [orpha.net]
Prognosis The prognosis for atrophic retinal holes is good. [eyewiki.aao.org]
Prognosis Patients with PPRCA have good visual prognosis with slowly progressive disease. In patients without macular involvement, visual acuity is minimally adversely affected. [eyewiki.org]
Etiology
Etiology The etiology of PPRCA remains unknown with a presumed initial inflammatory insult that leads to the slow developmental of the retinal findings. [eyewiki.org]
Etiology GACR is caused by homozygous or compound heterozygous mutations in the ornithine aminotransferase OAT gene (10q26) which codes for the ornithine-degrading, pyridoxal phosphate-dependent enzyme ornithine aminotransferase. [orpha.net]
These cases are usually associated with a worse prognosis compared to breaks of other etiologies. RRD is a common feature in several genetic syndromes. [institut-vision.org]
P athophysiology The etiology of lattice is questionable. It appears to be due to dropout of peripheral retinal capillaries with resulting ischemia, which induces thinning of all retinal layers. [eyecaretrust.org.uk]
Furthermore, consideration must be given to the risk of recurrence or involvement of the fellow eye based on the etiology (as described above). [asams.org]
